This paper describes the experimental study of the shaft oil feed mechanism of a rotary compressor. The oil contained in the shaft in which an oil pump is inserted is fed to the respective sliding surfaces of the subbearing section, eccentric section and main bearing section of the shaft by centrifugal force of shaft rotation. The oil feed pressure of shaft rotation is approximately 0.1 kg/cm2 ...

Background: Femoral shaft fractures are an incapacitating pediatric injury accounting for 1.6% of all pediatric bonyinjuries. Management of these fractures is largely directed by age, fracture pattern, associated injuries, built of the childand socioeconomic status of the family. We retrospectively evaluated the use of elastic stable intramedullary nail (ESIN)in surgical management of femoral s...

The objective of the drive shaft is to connect with the transmission shaft with the help of universal joint whose axis intersects and the rotation of one shaft about its own axis results in rotation of other shaft about its axis. Shafts must be exceptionally tough and light to improve the overall performance of the vehicle. Automobile industries are exploring composite materials in order to obt...

Inherited desmosomal diseases are characterised by skin and/or cardiac features. Dermatological features might be a clue in the determination of the underlying life-threatening cardiac disease. This article aims to propose a dermatological algorithm for the diagnosis of desmosomal diseases after a systematic review of published articles. Palmoplantar keratoderma (PPK), hair shaft anomalies and ...

BACKGROUND Both pelvic fractures and femoral shaft fractures are caused by high-energy injuries. When unstable pelvic fractures and femoral shaft fractures occur concomitantly, the optimal treatment method is controversial. The aim of this study was to establish a reasonable principle for treating such complicated injuries. METHODS Forty patients sustaining unstable pelvic fractures and conco...

This paper analyzes the effect of the fuzzy logic-controlled braking resistor (BR) on minimizing shaft torsional oscillations of the generators in a multi-machine power system. The influence of communication delay associated with the fuzzy controller input calculation on minimizing shaft torque oscillations is investigated. Global Positioning System (GPS) is proposed for the practical implement...

Current marketing of golf clubs places great emphasis on the importance of the correct choice of shaft in relation to the golfer. The design of shafts is based on a body of received wisdom for which there appears to be little in the way of hard evidence, either of a theoretical or experimental nature. In this paper the behaviour of the shaft in the golf swing is investigated using a suitable dy...
